Job 39:17 - Matthew Poole's English Annotations on the Holy Bible

Because God hath not implanted in her that natural instinct, and providence, and affection, which he hath put into other birds and beasts towards their young. And yet no man presumes to reproach me for making this difference in my creatures. And as little reason hast thou to blame me for afflicting thee, when others not so bad as thou for the present go unpunished; because I have no less authority over thee than over them, and can dispose of all my creatures according to my good pleasure. The great folly of this bird is noted by Arabic writers, who best know her, and that not only for this property of forsaking her own eggs, but also for other things, as that she eats any thing which is offered to her, as iron, stones, glass, hot coals, &c., whereas other birds and beasts have so much sagacity, as to reject improper and unwholesome things; that being pursued by the hunter, she thinks herself safe and unseen by hiding her head in the sand; for which, and other such qualities, it is a proverb among the Arabians, More foolish than an ostrich.
